chromium/FreeBSD9/amd64 unresponsive to input in gmail

[Luigi Rizzo]

at least on a couple of recent versions (25.0.1364.160 and 25.0.1364.152)
chromium on FreeBSD/9 amd64 seems to have problems with input
(keypresses and mouse events).
Symptoms are that in the compose windows input is not displayed
for 10+ seconds, then some characters randomly come out;
mouse clicks also act strangely, sometimes showing the cursor
(vertical bar between characters) in two places, and so on.

The same site works correctly under a recent Firefox.

I have seen reports of javascript-related failures on the
chromium forums too

so i wonder if others are seeing problems.

cheers
